I-IOISTING DEVICE.

Specification of Letters Patent.

Patented July 18, 19.11.

Application filed December 19, 1910. Serial No. 598,011.

To all whom it may concern:

Be it known that I, LEONARD ROMAN, a citizen of the United States,residing at Greenleaf, in the county of Meeker, State of Minnesota, haveinvented a new and useful Hoisting Device, of which the following is aspecification.

primary object of my invention is to provide a hoisting device for useon a farm, which is simple in construction and readily assembled and putin place, which, although inexpensive and easily kept in working order,is thoroughly eflicient, and which has an especial function in beingadapted to remove from a wagon body the wagon-box, h ayrack or otherconstructionthereupon and hold the same suspended in position for thewagon to be driven thereunder,-so that the box may again be placed onthe wagon when needed.

My invention contemplates the use of at least two hoisting devices,which may be of different character, as will be hereinafter pointed out,but which are necessarily related to one another in the functions forwhich they are designed, since it is the removal of one constructionfrom the wagon and replacing the same by another, for example,exchanging the wagon-box for the hayrack, that constitutes the essentialfunction of my invention. The average small farmer, having but one heavywagon, has frequent occasion to make the above indicated exchanges, andeach of said. occasions presents one of the most burdensome labors ofthe farm. Not only is it practically im possible for one man alone tomake the change, at least without danger of physical injury to himself,but even when" force enough is available to handle the heavy wagon-boxand hayrack, the strain upon these structures resulting from the unevenjarring manner in which they are removed from the wagon and depositedupon the ground, or vice versa, loosens and breaks the fastenings andinevitably largely shortens the useful life of both wagon-box andhayrack. My invention, at the same time, makes it possible for onepersoneven a young boy can operate the device-to exchange the structurescarried by a farm wagon with little effort and no danger of injury,either to the operator or the struc' 'tures exchanged, which are simplylifted without rack or strain of any sort.

The hoisting devices can, of course, also outside edges of the beutilized for lifting other heavy objects, as a hog or beef carcass forscraping or skinning, farm machinery to be loaded or unloaded, etc.

One form of my invention is illustrated the accompanying drawings, inwhich- Figure 1 is an elevation, viewed from the end, showing oneportion of the device after the same has removed a hayrack from thewagon, and the other part of the device in position to remove awagon-box from the wagon- Fig. 2 is a sectional plan on line 2 2 of Fig,1, with one of the castings in section to show the interior structurethereof. Fig. 2 is a side elevation of one casting, part of the samebeing in section. Fig. 4 is a detail view of the ratchet. Fig. 5 is anend elevation of a modification.

For a main support the post 1 is provided. This may be a piece of squaretimber, as shown, or a round post, or the trunk of a tree, or even theframework of the barn or other building may be utilized, and the postmay be formed of iron or other material, according to the requirementsof the particular situation in which my invention is to be used, but forgeneral purposes a square timber set into the ground several feet, so asto be immovably held therein, is to be preferred. The post may beprovided on opposite sides thereof with horizontal notches 2, into whichregister horizontal members 3 of two castings 4 and 5, respectively,said castings being clamped together and to the post 1 by means of bolts6. The castings 4-5 clasp the post 1 so as to leave a space 7 betweensaid castings, as

clearly shown in Figs. 1 and 2. By tightening the nuts on the bolts 6,therefore, the castings are clamped to the post 1 very rigidly, and ifat any time use of the device results in loosening the castings on thepost it is only necessary to tighten the nut-s to cause the wholemechanism to become perfectly rigid with the postagain.

Between the horizontal members 3 of the castings 4 and 5 extend outsidewebs 8 and inside webs 9, said webs 9 being adjacent the post 1, thebolts 6 passing outside of said webs 9 and the post 1, although close tothe same, so that when the two castings are bolted in clamping engagement with the post, as described, the resulting combination of partswill be peculiarly strong and rigid. In each of the horizontal members 3of the castings 4 and 5, are pro vided openings 10, which may becircular in form, or rectangular, or of other form, as desired, therebeing preferably one such opening at each end of said members 3,although a greater or less number of openings may be provided, itsometimes being desirable to provide a third opening between the webs 9for mounting a third hoisting means to be used independently when theother hoisting means on that side of the device are engaged in holdingsuspended a hayrack or wagon-box. Extending outwardly from, andsurrounding, the openings 10 are projections 11, which will have thesame interior form as said openings 10 but will preferably be of tubularexterior form. The correspondingly placed openings 10 in the top andbottom members 3 exactly register one above the other, so that saidopenings extending through the projections 11 form a practicallycontinuous housing or guideway for hoisting uprights 12, which have thesame cross-sectional form as that of said openings 10, and may be ofiron, wood or other material, as desired, an excellent article, wherethe openings 10 are circular, being ordinary cylindrical iron pipe, asshown, said uprights 1.2 being mounted to slide up and down freely insaid openings, while being constrained to keep a substantially verticalposition by the guideways formed by the projections 11. Additional meansto prevent deflection of said uprights 12 away from the post 1 consistsof pairs of arms 13 bolted to the post 1, one of each of said pairs ofarms passing on either side of an upright 12 and having journaledbetween said arms a guide-pulley 1 1, against which the outside part ofthe upright 12 contacts as it is normally positioned in the machine.

Each of the uprights 12 has therein a series of holes 15. A hoisting bar16 may be pivoted to the upright 12 by means of a pin 17 extendingthrough ears 16 embracing the upright 12 and any hole 15 which willposition the hoisting bar at the proper height for the particularpurpose desired, it being my intention to have said height of thehoisting bar adjustable. Where the weight to be lifted is unusuallyheavy, I prefer to use a second hoisting bar 18 to cooperate with thebar 16. The bar 18 is provided with a bifurcated foot 19 curved inwardlyso as to embrace the upright 12, to which it is pivoted by means of apin 20 passing through a selected hole 15 in the upright 12 and belowthe castings 4t and 5.

The bar 18 is provided at its other end with another bifurcated member21, within which is mounted an anti-friction roller 22, the hoisting bar16 riding on the roller 22 between the side portions of the bifurcatedmember 21. The side portions of said member 21 are drawn together at thetop and provided with a hook 23. The bars 16 and 18 may each be of metalcast or forged in one piece or the parts 16, 19 and 21 may be castingsor forgings to be attached to wooden bars. In this form of my invention,I mount a small pulley 21 between the ears 16' of the bar 16. From thehook 23, a flexible connection 00, preferably a rope or wire cable,extends over the pulley 24C to a windlass 25 in a bracket 26, adjustablymounted on one of the upward extensions 11. The bracket 26 comprises abase member 27 closely encircling the extension 11 and clamped theretoin any adjusted position by means of a set-bolt 28 screwed into andthrough said base member 27 and against the extension 11 of the casting3 or 4 The base member 27 has outwardly extending arms 29, 30, in whichis journaled the windlass 25. Said windlass consists simply of a shaftor rod, of metal or other desired material, having a squared portion 32at one end for the reception of a removable hand crank 33, a squaredenlargement 31 inside of said crank receiving portion 32 serving both tohold the windlass 25 from passing through its journals and also as aratchet, with which cooperates a pawl 34 loosely pivoted on the set-bolt28, and having a cut-out portion 35 corresponding in size and shape withthe squared member 31. Any of the wcll-kmnvn forms of pawl. and ratchetdevices may be used in place of that described above, but the describeddevice has the merit of being extremely simple and easy to make andapply, and being sure in its operation and not easily displaced whenholding the windlass against the pull of a weight suspended thereon.Vindlass 25 is held at the other end by washer 25 and pin 25".

Attached to the hoisting bars 16, either directly to holes 36 therein,or to an eye 37 depending from an encircling band or hoop 38, areconnections 39, having at the lower end thereof a ring 40, to which areattached two or more additional connections 41. To the lower ends of theconnections 41 are attached rings 12, carrying hooks 4-3. In preparingto hoist a wagon-box or hayrack, the windlass carriers 27 are turnedaway from each other, as shown in the upper part of Fig. 2, the uprights12 and hoisting bars 16 being correspondingly turned, and theconnections 41 from each bar 16 are brought to either side of the box orhayrack and a pole 414 placed beneath the same and through the rings-12, as shown, or the hooks 41 3 may be directly engaged with the frameof the box or rack. Upon turning the crank 33 on one windlass and thenon the other alternately, the bars 18 will be raised by the rope orcables :0, which, through cooperation of the rollers 22 with the bars 16will swing said bars upward on their pivots, lifting the rack from itsposition on the wagon, shown in dotted lines to the position shown infull lines, where it will remain until wanted for further use, the pawl35 acting against the ratchet 31 to hold the Windlass locked and therack suspended.

In general practice, for constructions of ordinary weight, I contemplatelifting the uprights directly and with them the load to be hoisted,either in the manner shown in the right-hand portion of Fig. 1 or inthat shown in Fig. 5. As shown in Fig. 1, bar 16 is pivoted to swingfreely upward. Flexible connection a" is attached to an up per eye -.t-5on the hoop 38, and passes over a pulley 4L6 journaled in the upper endof upright 12, down through the interior of said upright, which, forthis form of my invention, must be tubular, around another pulley 4:7journaled in the lower portion of said upright, and from there to thewindlass 25. Rotation of the Windlass will have a differential effectwith respect to the lifting point of attachment 37 of the connec tion39, both to swing the bar 16 upwardly on its pivot and to raise theuprlght 12 vertically.

In the form of my invention shown in llig. 5, the hoisting bar 16 isheld from downward movement on the pivot 17 by a cord or rod 48 attachedto the eye 45 and to a hole or other fastening device 49 on the upperend of the upright 12, The connection a is attached to an eye 50 fast onthe casting 3 or 4, from which point it passes down through openings 1nthe lower portlon of the upright 12 and around a pulley 51 j ournaledtherein to the Windlass 25. Operation of the windlass will thus act tolift the upright and its load vertically, but only at half the rate thatthe connection 00 is taken up, so that this will exercise a verypowerful lifting force.

Another method of restraining the bar 12 from outward deflection whenthe same is lifted vertically through the guideway 10 also shown in Fig.5. To the central supporting member 1 is secured by means of offsets and53, respectively, at the top and bottom thereof, a bar 54. Rigidlysecured to the slidable member 12 above the pivot point 17 of thehoisting arm 16, and near the top end of said member 12, is a member orpair of members 55, extending inwardly so as to straddle the bar 541-,and having rotatably mounted therein an antifriction roller 56 forcoilperation with the bar 5 1 to hold the said upper end of the member12 as itis lifted vertically from outward deflection by reason of theweight suspended from the hoisting arm 16, the roller 56, of course,riding along the inside of the rigid bar 54.

The operation of my novel hoisting device will be readily understood inconnection with the detailed description heretofore given.
